Moto-Master Fusion Dual Ring Rear Sprocket 51-Tooth Black for Suzuki (620013251)

Upgrade your Suzuki motorcycle’s final-drive performance with the MOTO-MASTER Fusion Dual Ring Rear Sprocket, Part 620013251. This 51-tooth sprocket combines a hardened, nickel-coated steel outer ring with an aircraft-grade 7075-T6 aluminum carrier to deliver a durable, lightweight solution for demanding riding conditions. The black finish provides a clean, purposeful appearance while complementing a wide range of motorcycle setups.
The specialized heat-shrink manufacturing process permanently interlocks the outer ring and carrier for a secure, precise assembly. Compared with a conventional aluminum sprocket, the hardened steel outer ring is engineered to provide substantially longer service life, while the aluminum carrier reduces weight compared with a standard steel sprocket. This dual-ring design helps balance durability and handling performance without sacrificing dependable chain engagement.
Each MOTO-MASTER Fusion sprocket is CAD designed, CNC machined, and laser cut using advanced manufacturing technology to maintain accurate fit and consistent operation. The carrier is color-anodized for added durability and resistance to wear, making this rear sprocket a practical choice for riders seeking reliable performance and long-lasting drivetrain components. Verify Suzuki model and fitment requirements before installation.
